Here is the link on the msdn site that talks you thru the code
http://msdn.microsoft.com/en-us/library ... de_samples
just cann't get all the pieces to work. Any help would be great. It compiles and links fine however I get an access violation if I proceed between these lines in the code
Code: Select all
system("PAUSE" ) ;
// Enumerate the streams and select
// terminals onto them.
IEnumStream * pEnumStreams;
ITStream * pStream;
system("PAUSE" ) ;
hr = pStreamControl->EnumerateStreams(&pEnumStreams);
// If ( hr != S_OK ) process the error here.
system("PAUSE" ) ;
If I can get this then the only other thing that can go wrong would be the TERMINAL part4 of the examples.
Curious though what the difference is in using connect or dial functions of ITBasicCallControl to place the phone call? Maybe I should be using dial to use it with V.92 modem and connect if I was useing H323 or SIP or VOIP app...etc.
Thanks again for any help
I know it is alot to look at.
Remember it is this
Code: Select all
hr = pBasicCall->QueryInterface(
IID_ITStreamControl,
(void **) &pStreamControl
);
Cann't establish what why it is not ok am I not seting the parameters correctly if so what do I use?
Note also that if you want to download and test it you will have to change the 5555555 to a vailed phone number. And I was in VS2005 studio , windows XP SP 2 with DirectX 2008 installed ....
